MATTHEW INGRAM, OF MANCHESTER, COUNTY OF LANCASTER, ENGLAND.

FIRE-PLACE QR STOVE.

SPECIFICATION forming part of Letters Patent No. 257,716, dated May 9, 1882.

Application filed J annary 13, 1882. (No model.) Patented in England May 3, 1881, and in France November 2, 188].

To all whom it may concern: Be it known that I, MATTHEW INGRAM, of Manchester, in the county of Lancaster, England, have invented a new and useful Improve ment in Fire-Places or Stoves, of which the following is a full, clear, and exact description. The object of my invention is to construct stoves, grates, fire-places, and kitchen-ranges in such a manner as to enable coke, anthra: cite, and common or inferior coal to be used, consuming their own smoke 5 also, to prevent downdraft and to heat the roomor rooms by means of hot air, andalso to properly ventilate such room or rooms.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of one form of my improved fire-place or stove. Fig. 2 is a sectional elevation of the same. Fig. 3 is a sectional plan view taken on the line so a: of Fig. 2. Fig. 4. is a similar view, showing a modification of the air-heating chambers. Fig. 5 is a detailed sectional elevation, showing the gills or baffle-plates fitted in the air-heating chambers and Fig. 6 is a sectional elevation,

showing my invention applied to kitchenranges.

A represents the main combustion-chamber; B, the auxiliary combustion-chamber, and O (l the air-heating chambers. The main combustion-chamberis provided with the ordinary front bars, a, for keeping the fuel in place in the chamber, and is fitted with .the bottom I), which by preference is made solid, of fire brick or clay, or any other suitable material. In front of the auxiliary combustion-chamber is placed the door d, which is fitted with an airvalve,'c, for regulating the supply of air to the auxiliarycombustion-chamber. The door at is used for clearing out any dust or ashes from the auxiliary combustion-chamber before lighting the fire. The auxiliary combustion-chamber is divided by the diaphragm f, which is of metal or other suitable material, and reaches nearly to the door d, and supports the lower end of the fire-clay back f of the fire-place or stove. Between the back f and the back of the bottom b of the main combustion-charm her is formed the backward] y and downwardly curved passage or flue g, which communicates back flue, h, formed behind the back f, andi5 leads up to the chimney.

D is a damper, placed at the mouth of the chimney above the main combustion-chamber, which is to be opened when the fire is started and kept open until the air in the chimney has become sufficiently heated to create a draft. This damper is then to be closed, and the damperE in the flue h opened, so that the draft will be through the auxiliary combustion-chamber. An additional opening is made at h, as shown in Fig. 2, which maybe opened and closed by a suitable valve, or may be a fixed opening, and is for the purpose of taking away any smoke that may fail to pass through the flue g into the auxiliary combustion-chamber when the damper Dis closed. Before lighting the fire the damper D is opened, and the fire is allowed to burn for some time. When the fire has become sufficiently warm to cause a suitable current or draft the damper D is closed. This causes the products of combustion to descend from the back of the main combustion-chamber, as indicated by the arrows in the drawings, into the auxiliary combustion-chamber, and then upward into the flue h, as also shown by the arrows. The force of the current can be regulated by the damper E, which isin connection with a suitable handle, 0, of any convenient form, reaching to the front of the stove or fire-place. The gases, smoke, and products of combustion from the main combustion-chamber, as they descend the flue g, are caused to burst into flame, furnishing additional heat by coming in contact with a supply of air entering the auxiliary combustion chamber through the valve 0.

The side air-heating chambers, (l O, are provided or constructed with the gills or baffle plates j j, as shown in Fig. 5, to cause the air to pass in a zigzag course through the said heating-chambers. The external air :is drawn into the heating-chambers through the flue or cold-air passage 70, from whence it gains access to the side chambers, as indicated by the arrows in Fig. 5. The upper ends of the heating-chambers terminate in some cases in a space above the stove or fire-place, as shown at Z, Fig. 6, which is faced with open ornamental work,or with valves or openings which open into the room, in order to let the warm air enter the room and prevent draft from windows or doors. In other cases these flues may be made to Warm bed-rooms and other rooms by means of suitable pipe-connections or flues leading thereto.

In adapting my invention to kitchen-ranges the boiler L may be fitted,in the manner shown in Fig. 6, to form the back of the fire-place and the division of the auxiliary combustionchamber, and suitable ovens may be formed in the range on each side of the boiler and fireplace for baking purposes.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- In a fire-place, the combination, with the grate a, b and combustion-chamber A, of the downfluc g, the combustion-chamber B, having valved door 0 d, and the flue h, leading to chimney, as shown and described.

The above specification of my improvement in stoves signed by me this 21st day of December, 1881.

MATTHEW INGRAM.
